Clinical and Angiographic Outcomes of Patients Treated With Everolimus-Eluting Stents or First-Generation Paclitaxel-Eluting Stents for Unprotected Left Main Disease
2012
Objectives The goal of this study was to compare the outcomes of patients treated with everolimus-eluting stents (EES) with outcomes of patients treated with first-generation paclitaxel-eluting stents (PES) for unprotected left main disease (ULMD). Background No data exist about the comparison of these 2 types of stents in ULMD. Methods The primary endpoint of the study was a 1-year composite of cardiac death, nonfatal myocardial infarction, target vessel revascularization, and stroke (MACE). Secondary endpoints were 1-year target vessel failure (TVF) and 9-month angiographic in-segment restenosis >50%. Results From 2004 to 2010, a total of 390 patients underwent ULMD percutaneous coronary intervention (224 received PES and 166 EES). The 1-year MACE rate was 21.9% in the PES group and 10.2% in the EES group (p = 0.002). TVF rate was 20.5% in the PES group and 7.8% in the EES group (p Conclusions EES implantation for ULMD is associated with a reduced incidence of 1-year MACE, TVF, and restenosis as compared with PES implantation.
